REFRIGERATING DEVICE.

Application led May 19, 1924. Serial No. 714,286.

and useful Refrigeratin' Device, of which the yfollowing is a specication.

`My invention relates to the art of refrigerating'devices. Moreparticularly, my 1nvention relates ,to a refrigerating device whichkprovides; (a), for a one-way active positive circulation of the air inthe cooler; (b), for a .refrigerating means which reduces the moisturecontent ofthe air; ,and

(c) eliminates .the coating ofthe refrigerating means with ice.

For purposes of illustration,-my invention will be explained by settingforth the same as applied to a meat preserving device, but it is notl tobe considered as limited to any such specific use, but includes all usesinvolving similar problems and conditions.

Circumstances may make it desirable to have the refri erating means in achamber commonly cal ed a l the cooler, i. e., that part of therefrigerating compartment disposed to accommodate the products to bepreserved. Many such refrigerating plants, as now built, have such`lofts, and the same may be readily convertved to embody my invention asherein set forth. Such refrigerating means, as heretofore designed, havebeen known generally as the open brine system. Serious objection obtainsto such in that said system does not eiiiciently provide for removingthe moisture content of the air in said compartment, and does notefliciently cool the air and provide for such active positivecirculation as to prevent the condensation on the walls and ceiling ofthe cooler and the coating of the refrigerating means with ice.

These and other inherent objections, it is, in general, the primaryobject of my invention to overcome. Alprimary object of my invention isto provide a refrigerating de- .vice which embodies a cooler, in whichthe air,-having its moisture content reduced, is

, actively positively'- circulated therethrough in one direction only atsuch a temperature that objectionable vcondensation onthe walls orceiling and coating the refrigerating means with ice is eliminated.

Further primary objects of my invention are to provide a refrigeratingmeans which oft separated from will prevent the coating of the coldestparts with ice, and provide a sanitary refrigerating 'device,-sanitaryboth as respects the parts being preserved, being characterized by a lowhumidity, and as respects the health of the employees.

The above mentioned general objects of my invention, together withothers inherent in the same, are attained by the device illustrated inthe following drawings, the same being merely a preferred exemplary formof embodiment of my invention, throughout.

which drawings like reference numerals indicate like parts: Figure 1 1sa view in vertical section of a refrigerating device embodying myinvention;

` Fig. 2 is 'a-view in elevation andvertical section on'dotted line 2, 2of Fig. 3;

Fig. 3 is a view in elevation on line 3, 3 of Fig. 1; andA Fig. 4 is aview in elevation on line 4, 4 of Fig. 1.

A heat insulated compartment 5, formed by walls 6,7, 8, and 9 (front andback walls not shown), is divided by heat insulated partition 10horizontally disposed into a lower chamber or cooler 11 and an upperchamber or loft, divided by a vertically disposed the oppositelydisposed walls 6 and to I provide air passages 19 and 20.

Partition 12 may be provided witha step 21, from which is suspendedvertical .cylinders 22, preferably supportedv by angle brackets 23mounted on trough 18. .Said

cylinders 22 are preferably disposed in y. 100

spaced-relation with .respect'to that portion of partition 12 below step21.

A refrigerating liquid supply pipe24 is provided, `preferably in theforward `loft 14, having pipe connectors 25 with spray nozzles 26axially disposed in the upper `end ortionof each of the verticalcylinders 22. alve member 27 regulates the rate of flow of therefrigerating liquid. Withdrawal pipe 28 connects with trough 18.

Perforations 29 may be supplied in the upper end ortions of thecylinders 22, and these may e surrounded by sleeve disposed in s acedrelation to the cylinders 22.

The mo e of operation of a device embodying my invention is as followsz' The refrigerating liquid from supply pipe 24 is f orci ly jetted intocylinders 22, and said liquid is disposed as a coating over the insi esurface of said cylinders. The liquid is dischar ed into the trough 13,from which it is wit drawn through withdrawal pipe 28. The Jettingaction forcibly draws or sucks in the relatively warm air from the backloft chamber 15 and thoroughl removes the' heat therefrom, ejecting theco d air from the bottom of said cylinders 22, which cylindersconstitute the only direct communipassageway 20.

Y convey cation means between the back and forward loftA chambers. Thecold air then passes downwardlirthrough passageway 19 to the cooler 11,t ough which it is positively actuated by reason of the suction createdby the jettin action already described, so that after it a sorbs theheat f-rom the products in the cooler', it asses upwardly through hejetting action is supplemented in creating the flow of air byavity,-cold air naturally fallin to the ower levels while warml airnaturaly rises. Thus, an active positive circulation is created, whichmaintains an eicient refrigeration in the cooler, and preventsobjectionable condensation on the under side of partition 10, whichforms the ceiling of the cooler 11. The moisture absorbed in cooling theroducts in the cooler 11 is promptly to the back loft chamber andcondensed in the cylinders 22 during the exposure thereof to therefrigerating Huid, in which fluid the said moisture is withdrawn by,lplipe 28 (from the compartment 5.

- is condensing and removin of the .l moisture content from the air by te means prevent t ofrefrigerating herein set forth cooperates with theositive circulating 'of the air to prevent o actionable condensation onthe ceiling of t e cooler, which o ccurs in refrigerating means of theloft type of present practice design. Moreover, the keeping of therefrigerating Huid in the trough and not allowing it to run down theupper surface of the partition -10 keelps from rendering said partitionso cold t at it condenses the said moisture content to any ob'ectionableextent. Practically considere such condensation is eliminated in thedevice embodying my invention.

Although cylinder 22 is preferably disposed inthe forward loft, wherethe temperature of the air is cold, nevertheless, there is a tendency toform an ice coating on the uplper ortion of the cylinder. To

is, preferably provide-perforations 29 in the upper end portions of thecylinder 22. This resultsin a portion of the refrigerating liquidflowing'4 down the outside of the pipe and supplying it with anon-freezing coating, so that the di'iculty of an ice coating formingthereon is eliminated. To cause this liquid to operateevenly over theouter surface of the cylinder and to keep the same from-splashing outinto the chamber, sleeve 30 is preferably provided. The amount of saidliquid flowing down the outside is kept to a minimum and just Sullicientto maintainl the temperature on they outside of such a degree as toavoid the' tendency to form a coating of ice thereon.v

Obviously, changes may be made in the form, ydimensions and arrangementof the parts of my invention, without departing rom the principlethereof, the above setting forth only a preferred form of embodiment.
